. I My invention relates to silo fillers, and par- I ticularly to the pipes thereof, which I so improveas to render them more effective under "the varying conditions commonly incident to Ill] the operation of such machines, whereby the long filler pipe can be readily disconnected from/the fan casing to remove clogged materialtherefrom, and as readily returned to normal position, aswell as otherwise adjusted, while other advantages will be apparent from the following description.

fIn the accompanying drawing, forming .part hereof, Figure 1 is a rear elevation of a portion of the fan casing, which terminates in a boot as is common, and towhich a pipe section is connected; Fig. 2, a side elevation of said structure and to which myimprovements are applicable; Figs. 3 and l, detail elevations illustrating the adj ustability of the piping;

Fig. 5, a side elevation of a silo and filler illustrating the application of my improvement; and Fig. 6 is a horizontalsectional view taken on the dotted line 6-6 in Fig. 5. i

In said drawing the numeral 5 indicates a,

fragmentary ortion of the fan casing, and 6 a boot there or, which is provided with a reinforcing flanged ring 7 Itis customary to attach a short pipe section 8 to the boot 6 by securing its lower flanged ring 9 to the ring 7 by means of bolts, while the lower member 10 of the upper pipe sections is'bolted and supported by the flanged ring 11 at the upper end of the outlet 8 in which manner the silo pipe becomes, a continuous structure bolted or otherwise connected together section by sec-.-

tion. In my improvement, however, it will be noted that the lower end of the section 8 is pivotally connected,'at 12, to its ring 9 at diametrically opposite sides, by which means 7 the section, as well as the remainder of the v pipe supported thereby, may be rocked from side to side, and that its upper end is also pivoted, at 13, to the upper ring 11 so that it mayby swung slightly in a forward and backward.

direction in relation to the silo, whereby said section is capable of variable movements andis in effect what is commonly called a universal pipe joint, the function of which will appear. Instead-of securing the boot and outlet together by rings and bolts I connect these sections. I

to varying positions sections by means of a collar 15loosely mount ed on section 8 and which is providedatoprequired tightly drawthe links sufficiently to efiectively bind the collar 15v about the rings, but it will be understood that any practical means may be employed for detachably assemblmg the collar and .meeting ends of said As is well known, silage is ofa heavy sluggish character, and during the operation of cutting and'discharging into the silo,

- 25, 'it'mu stbe" forcibly propelled a comparatively long distance, and I occasionally the material becomes packed and chokes the :pip-

ring, in which circumstance itis-necessary' to disconnect. the outletg8 from the boot (Sand relieve-the choked condition by' suitableim- .plements, and' then bolt the parts together.

With my improvemenahowever, it. is. but a: simple matter-to manipulate the levers 20 to release links 16 when the ring may be raised to the position indicated bydotted lines. in Fig.2 and suspendedlby the links,-whi ch,-are swung upwardly to engage hooks 21 on :the

side of the outlet section whereupon the outa let 8 supporting the upperpipe, sections can be readily shifted and supported on theboot Gasindicated in Fig. 3"ani d ready access thus obtained to the boot or pipingforremoving packed material therefrom. In some cirCu Y stances, however, it will notbe necessary to fasten thecollar 15,,aswhfen it is positioned to overlapthemeetingends 71, 9, ltrWll-L have served to center a section'as 8 inrelationto the boot 6 or other section, and prevent lateral displacement of such section; and] further, when thus assembled, the relation ofsaidcem tering collar to the rings 7, 9, affords a turntable action whereby the long discharge pipe '10 maybe rotatedwithin the collar so that its distributing portion 10 may be adjusted a d c d by h f db elevated by tackle), but by providing the section 8 in vpivotal relation to boththe boot 6 and the piping 10such flexible connection permits ad ustability of the upper piping, s-

' I 7 that if conditions require 1t may beset at;

angular positions between the fan casing and the siloinlet 26, or the joint 8 maybe ad 15 justed at an angle to compensate for any irregular 'positioning of the filler 27, and an- ;gular positions laterally'of pipel0 relative to the silo thus avoided. As the piping is thus-flexibly connected to the boot 6 in the 2-90 manner described it will be. apparent that tions'according to ground-and other conditions to accommodate the silojfiller 27 in '6-' lation-to the silo 25, many of which silos, as

indicated in Fig. 5, embody projectingbases,

" as 28, which prevent the filler frombeing V set-closely-adjacent thereto,and therefore by being enabled to adjust the long piping laterallyand farther from and closer to the silo i fore be set according to the most favorable 2.
